The purpose of this study was to determine the effects of the structure of skeletal muscle of lower extremities on function, activity, and partici-pation of children with cerebral palsy. The subjects were 38 hospitalized patients and 13 infants with normal development. The following clinical measures were used for assessment of activity daily living and func-tional level of gross motor: Gross Motor Function Classification System (GMFCS), Gross Motor Function Measure (GMFM), Wee Functional In-dependence Measure (WeeFIM), International Classification of Func-tioning Child and Youth (ICF CY). Muscle thickness and strength of knee extensor and ankle extensor were collected using ultrasonography and manual muscle tester. Following the results of ICF CY evaluation for body function, activity, learning and application of knowledge, communica-tion and environmental factors showed a decline (P<0.05). Significant differencesin the thickness of muscle was observed according to the GMFCS level, thickness of knee extensor and ankle extensor of cere -bral palsy (P<0.05), and clauses of self-care, activity, mobility, ambula-tion, communication, and social acknowledgement (P<0.05). Following analysis, results showed negative correlation in the thickness of muscle, muscle strength, major motor function, daily activity and participation; the score of ICF-CY was shown to decline due to the high score for dif-ferences in thickness of muscle, muscle strength, WeeFIM, and GMFM. The thickness and muscle strength of lower extremities affect main func-tions of the body and improvement of muscle strength of lower extremi-ties may have positive effects on social standards such as activity and participation of cerebral palsy.
